Can someone please straighten me out on 62 gn. green tip ammo.

1. With just about everyone having access to at least some type of body armor, say a plate holder and plate from the surplus shop, is this ammo even relevant anymore?

2. Both of my rifles have 1:7 in. twist. I'm working under the assumption that the green tip ammo was designed for short ranges, say 150 or less and much less for penetrating a plate. Will 1:7 twist stabilize this round, and is that question even relevant.

Any thing else you can tell me, or feel like adding, please do. Also, is the black tip available to civilians? I think it's got a tungsten tip?

I would just go buy a few boxes and rig up some tests at the range, but I can only find it in full cans around here, and I'd like to try a couple of rounds, say 100 or so, before committing to a whole ammo can, only to find it may not shoot worth a crap.

Thanks much in advance for your valuable time.

PS... Those would be 16in barrels if it makes any difference.
